To .Z 'ifi/lacet 'may concern own-'that We, marne @DEN and migrer, citizens of the United ning at Columbus, in the county u and State of Ghio, have invented and useful improvements in i, of which the following is wel atesto milking apparticuarly the ramiied claw. ii r ,ntion is to provide clair `which not only Will be ,tseu in construction, but will be. more use` positive in operation and te out of repair. her object of the invention is to ible yielding member, the com- -f which may be independently suit the convenience of the operie condition of use.

`adapted for use in conjunction With a sucdescribed. The suction means or pulsator,

per Se, forms no part of the present invention.

The claw or cluster is further adapted for use in conjunction with teat cups of the pneumatic pulsating or vibratory type embodying in addition to the main suction chamber an auxiliary chamber to and from which the air is alternately admitted and exhausted, thereby causing a Vibratory ac# tion of the Walls of the inner or suction chamber. lVhile for purposes of illustration a teat cup has been shown-in detail in the drawing, such teat cup, per se, forms no part of the present invention, but as at present advised Will form the subject matter of a separate application.

Referringl to the drawings, a, 6, c and d are the teat cups comprising a single group which may be of any suitable construction of the pulsating or vibratory type; Such teat cups usually comprise a shell or housing l, preferably of metal, Within which is a 'flexible tubular suction chamber 2, prefer-y ably of rubber, rubberized fabric, or other' exhausted from the chamber 3. The admission of air to the chamber 3 compressesv or of the suction chamber 2 which, as before stated, 1s maintained under partial vacuum. The exhaustion of the chamber 3 whereby the air pressure within the chamber 2 and the'chamber 3 will equalize permits the flexible Wallsof the chamber 2 to expand or return to normal. The device forming the subject matter hereof is not limited to the particular style of teat los ' cup shown in the drawin s but may be used `With any construction o pulsating cup. 'To this end the cluster or claw forming the subject matter hereof comprises a main or milk conduit 4 from which project laterally angularly disposed branch conduits v5-5-5 each of which is connected-by a flexible conduit 6 with the suction chamber 2 of the corresponding teat cups, a, b, c and d. It will thus be seen that the main `or milk conduit is common to all the teat cups, each of which is in direct communication there-l .withA The main milk conduit 4 is prefervably'formed from rigid material such as metal, composition,' hard rubber, bakelit'e or some other similar product. In order 'that the milk tube or conduit 4 may be readily cleansed, it is provided at its extreme ,endV with a 'movable cap Llivliich enables a cleaningdevice to be passed entirely 'through the tube or conduit when disconnected from the hose throughgivhich' the milk is conveyed L to the receptacle.,` Extending parallel with the milk conduit 4, are a plurality of flexi- 'ble independent 'air conduits. ln the pres-v ent .instance but ,two of theseflexible air 'conduits7`=and,8 have been shown.. lt wilhbe obvious that Iif so 'desired one may be pro- "i vided' for each lteat cup .ii/hereby the teat cups mayb'eindepe'ndently operated in suc-A cession. 'Initheembodiment shown in the' 4drawing cach 'air conduit 7 and 8 comprises Ya length of rubber, fabric or otheriiexible introduced intothe. extreme' end of each flexible-independent conduit 7 and' 8, while...

hose; at itsfextreme' end each conduit is provided with "a lsubstantially Y-shaped connect1on comprlsing three integral or connected nipples 9, 10,' and 11,*projecting in such relationv from va'` common'or central connect- 0in-t that each nipple or connection exten s 1 l'a-teral1yjinA relation Withthe :other two nipples.v .In 'other words `the several 'branches' or nipples are not located in a single commoniplan'e, butA one nipple or con-v nection lpriects substantially perpendicular to'the plane in which the .remaining two nipplesare'located. One of the nipples is the remaining an'gularly disposed nipples or connections are.co'nnected with" branch conv .duits 12 which communicate with the air or pulsation chambers of a pair of teat cups. Bythis arrangement each'independentnexi- 1 bl'e'con single pair of teat cups .independent o the remaining 'pa-ir of cups. The cupsmay be'.

connected-With airconduits and A8` either in parallel relation" ordiagonally, viz., the

tv vo right hand and twol left hand.` cups may Abe connected to separate independent iexible conduits or the two rear or the two for- Ward cups may be connected 'to separate conduits, or in lieu or this arrangement th'ev diagonallydisposed cups may be connectedy with the same conduit. The latter arrange-v l71. in 'ateat'cu duit 7 andB communicates vwith a' jaaesse ment is to be preferred. The conduits 7 and 8 are so connected to the pulsator or control device, that the particular tcat cups communicating with the respective conduits will be alternately operated.

The milk conduit 4: and air or'actuating media conduits 7 and 8- are yieldinglyheld in grouped relation one with the' other whereby each of said conduits may be adjusted longitudinally in relation with the other, by means of an encircling ring or band 12. This ring is preferably of metal but may be of any suitable or convenient material. lt may be' either rigid or flexible. The several conduits cannot escape from this retaining ring or encircling band l2 inasmuch as the branch conduits 5, 10, and il project radially beyond the limit of ythe ring l or band. These branch conduits therefore, comprise limiting stops. Thus' While the several conduits are "held in grouped relation they may be independently adjusted longitudinally as is .found most convenient.

From the above description it will be apparent that there is thus provided a device particu]arfeatures of advanta e before enn-` nierated as desirable but which obviously is susceptible of modification inits four.,

proportion, detail construction or arranre- .f

i' vention is not limited toiany specic details, -but that the means and construction herein vdescribed comprise'but one mode of putting the invention into effect, and the invention vis therefore claimed broadly in any of itsA possible forms or modifications Within the scope of the appended claims.' Having thusdesc'ribed our invention, what duit common to all the cups, a plurality of conduits for actuating media, said conduits 1 i being respectivelyl connected to dierent teat cups, and a flexible connection between the actuating media conduits and the milk conduit. v
